y=13y+12,6y-9y=13y+12,6y−9

3 Break down the problem into these 2 equations.

y=13y+12y=13y+12

y=6y-9y=6y−9

4 Solve the 1st equation: y=13y+12y=13y+12.

i dont know what u said so i solved for y

Answer:

y = 1/4

Step-by-step explanation:

Yo no comprehendo espanol mucho, but I'll try

12y + 15 + y - 36y - 9 = y

Rearrange

12y + y (-y) + 15 (-15) - 36y - 9 (+9)= y (-y) (-15) (+9)

12y - 36y = - 15 + 9

-24y = - 6

Divide both sides by - 24 (Take note of the signs (+) (-))

-24y/-24 = - 6/-24

y= 1/4

Answer:   1.50+5m=76.50 m=15

Step-by-step explanation:

The required equation is 1.5 + 5m = 76.50 and distance travelled is 15 miles.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

pick-up fee = $1.50 plus $5 per mile

Since, m is the number of miles in the taxi ride

So, equation for pick-up fee for m miles,

pick-up fee = $1.50 + $5m

Now total fare = $76,50

Thus, required equation to determine m is given as,

1.50 + 5m = 76.50

Subtracting 1.5 both the side we get,

1.50 + 5m - 1.5 = 76.50 - 1.5

⇒ 5m = 75

or, m = 75/5

⇒ m = 15

Thus, the required equation is 1.5 + 5m = 76.50 and distance travelled is 15 miles.

[tex]\huge\boxed{\sf x = 20}[/tex]

Step-by-step explanation:

=> Since it is an equilateral (Having all angles and all sides equal)  triangle, so every angles will be equal to the other.

=> The sum of the measures of interior angles of triangle add up to 180 degrees.

So,

3x + 3x + 3x = 180

9x = 180

Divide both sides by 9

Answer:

Table shown below

Step-by-step explanation:

Linear Modeling

It consists of finding and using the equation of a line to represent the behavior of a real situation in numerical terms.

We are given the model of the charges for a satellite radio company that charges a fixed fee of $36 for installation and a variable fee of $42 per month for use.

The model is written as:

C(m) = 36 + 42m

Where m is the number of months.

For m=1:

C(1) = 36 + 42(1)=$78

For m=2:

C(2) = 36 + 42(2)=$120

For m=3:

C(3) = 36 + 42(3)=$162

For m=4:

C(4) = 36 + 42(4)=$204

For m=5:

C(5) = 36 + 42(5)=$246

The calculations are resumed in the table shown below.

Answer:

y=2x-11

Step-by-step explanation:

Answer:

I'm getting

y=-7x+8

The 7 is negative for me..You should maybe try yourself too and see what you get I might have made a mistake

Step-by-step explanation:

I'm guessing you live somewhere in the U.S. so I'll use the equation you use there

Equation:

[tex]y = mx + b[/tex]

[tex]m = \frac{y1 - y2}{x1 - x2} [/tex]

first pick two points

I'll pick (0,8) and (1,1)

[tex]m = \frac{8 - 1}{0 - 1} = \frac{7}{ - 1 } = - 7[/tex]

this means that the slope is -7

So far the equation will look like this

[tex]y = - 7x + b[/tex]

to get b pick one point, I'll pick (0,8) and replace y and x

[tex]8 = - 7 \times 0 + b[/tex]

when you solve this you'll get b

[tex]b = 8[/tex]

So the equation will look this

[tex]y = - 7x + 8[/tex]

Answer:

The friends split the bill at 15.32$

Step-by-step explanation:

So to find how much each paid you would take the bill total and divide it by the amount of people in this case three

And for the equation it would be 45.96/3=15.32$

The equation to model the solution to the problem would be; 3x = 45.96. the friends split the bill at 15.32 dollars.

An equation is an expression that shows the relationship between two or more numbers and variables. A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be one degree.

Given that the dinner for Lorenzo and his 3 friends costs $45.96.

To determine how much each paid would take the bill total

Therefore, we will divide it by the number of people in this case three

3x = 45.96

x = 45.96/3

x  = 15.32$

And for the equation would be; 3x = 45.96

Answer:

48 orders

Step-by-step explanation:

so 10 dozen is 120 because 12(10) is 120. we first subtract 120-28, which is 96. divided 96 by 2 to get 48.

equation: (12(10)-28)/2=x

Answer:

46 orders.

Step-by-step explanation:

(10*12) - 2x = 28

120 - 2x = 28

-2x = 28 - 120

-2x = -92

x = -92/2
